The discovery of superhard tungsten tetraboride is further evidence for the promising design approach of covalently bonding incompressible transition metals with boron. While WB 4 was first synthesized and identified as the highest boride of tungsten in 1966, [ 52 ] it was only recognized as an inexpensive superhard material in 2011.

S1, a medium-carbon shock-resisting steel tool steel which combines moderate hardness with good impact toughness. Carbon content 0.40 - 0.55%. [11] W1, a water hardening tool steel. High carbon content. W2, a tool steel that holds its edge quite well but is not very tough.
Cutting tool materials are materials that are used to make cutting tools which are used in machining (drill bits, tool bits, milling cutters, etc.) but not other cutting tools like knives or punches. Cutting tool materials must be harder than the material of the workpiece, even at high temperatures during the process.
Glass cutter, showing hardened steel cutting wheel (far left), notches for snapping, and ball (on end of handle) for tapping. A glass cutter is a tool used to make a shallow score in one surface of a piece of glass (normally a flat one) that is to be broken in two pieces, for example to fit a window.
Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.
Kennametal, a metal-working and tool company based in Latrobe, PA, USA, developed the first titanium carbide cermet with a 19 megapascals (2,800 psi) and 100-hour stress-to-rupture strength at 980 °C. Jet engines operate at this temperature and further research was invested on using these materials for components.
Liquidmetal has also notably been used for making the SIM ejector tool of some iPhone 3Gs made by Apple Inc., shipped in the US. This was done by Apple as an exercise to test the viability of usage of the metal. [11] They retain a scratch-free surface longer than competing materials, while still being made in complex shapes.
